Ok this error is because you have not started the document with the <?php tag.

Although this is a common mistake it is made by many people.

Make sure there is no blank space in the file before the php tag and make sure that you don't echo or print anything to the browser before the header function executes.

Well I have used only one php file for the whole application So php tags are there as per they should.

I just use cases for doing different things.

I wrote :
<a href=phpFilepath.php?action=tagClicked&uploadId=2 target='_blank' rel = 'tag' > associatedText</a>

And there is no echo after the linked text is clicked.

OK two problems that jump out at me from the scripts you sent is that you have a character before the first tag in the library and also you have a blank line at the end of it. Because of this it will send all headers down before you can modify them.

Ok I have been reading the function where you get data from the database. One thing that really strikes me is that you don't validate the data before you pass it to the database. This is incredibly important because otherwise people can execute any SQL commands they want (including stealing other people's files).

Please go to http://www.phpsec.org[^] to learn more.

I have now emailed you an updated copy of the script which should fix the problem you have but will not fix the security problem.

That is peculiar. There is one thing that jumps to mind, you haven't stated that the "Content-type" header is

"application/pdf". <br />

Can you confirm if you have done this or not? You can check by stopping the file from going down and then printing the value of the $fileType variable.

You could also try making sure that the file name ends in .pdf, this is very important on a windows machine.

Sometimes the browser will just not give the type. An easy way to determine it after it is uploaded is to try matching the extension (ie .pdf) to a certain format and then use that if type = null.

How to make page for members at the time they where created?

VinuLite5-Mar-07 22:14

Using PHP Technology.

When adding a member an individual page will automatically be created for that member, at say www.testproject.com/vinuMuraleedaran provided that the member’s name is vinu Muraleedaran.

You mean create a directory for the user when they are created?

That is a bad idea 90% of the time. I would advise having a single page that populates its value depending on the user.

Ya I also want like that. A single page that populates its value depending on the user. Already I had made a single page for this and iam passing the id's of the users as query string. The page will display the content of that particular id. But in the URL i need the name of that particular user(The name of that user in which i am passing as query string)

the function does not find for the pop up blocker ON/OFF in my application. Its is IE7.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
